To all *whomit mayconceriif -Be it known that I, Jorn\ L. Pennies, a

citizen'of the United States, and a resident of the city of Chicago, county cf Cook, and T State of Illinois, have invented certain new and useful Improvements "in Priming Devices; and I do hereby declare that the following is a fulkclear; and exact description of the same, reference beinghad to the" ac companying'draWingSE and to the numerals.

of reference marked thereon, which forn a part of this specincatlon.

. Oftentinies internal fcombustion engines are difficult to start owing to the introduction' thereto of a poor fuel mixture from the carbureter, and consequently, the engine.

must ibe cranked'a number of ti'meskto introduce and eject various charges of mixture until one proper for ignition is introduced. However, the difliculty in starting is not always the 'fault'of the carbureter, as the latter may be adjusted to introduce proper mixtures to the engine when the same is running, and the cylinders are warm, whereas atmospheric and climatic conditions may have an effect uponthe'engine and carbureter as to prevent immediate starting of the engine when the same is cold. It is a well known expedientywhen such difficulty is encountered, to prime the cylinders of the motor by introducing liquid hydro carbon through pet cocks in each one of the cylinders, after which, by switching on the spark and giving theengine a slight turn, it is started in operation.

. This invention/relates to a means for priming each cylinder of'the motor by mechanism attached on the dash, thereby not re-.

quiring the operator, as, for instance, in an automobile, todismount from his position to raise the hood of the car or be otherwise inlconvenienced in the priming operation.

'It is an object "of this invention also. to provide a device'for pumping hydro-carbon .fuelinto the various cylinders of the motor regardless of the conditions of pressure therein. 1 a

' It is also an object of. this i'nventionto provide piping connections for each cylind er' of the engine, whereby fuel maybe pumped therethrough under pressure, to and into each one of th 1 ylinders consecutively, .as,fo'rinstancepin"th 'itiring order, or as other ise desired. c M 5 51501 11 object of this invention to Bessemer a device tvhe'rein'a movement of a Specification of Letters Patent.

plunger serves to open ail-admission valve for hydro-carbon fuel'into a cylinder containing the plunger, and wherein reverse movement of said plunger serves to force saidfuel under pressure, outwardly from said cylinder to the respective cylinders of a hydro-carbon engine; I

lt is also an object of this invention-to provide a device for introducing fuel under pressureto the respective cylinders of'a hydrocarbon engine and wherein suitable check valves are; provided in. the pipe lines connected" to the cylinders to permit an increase of pressure therein to any desired amount, determined by the number of actuations of the plunger.

It is furthermore an. object of this invention to construct a device wherein fuel maybe introduced to the cylinders of a l1ydrocarbonsengine under pressure independently of the carbureting mechanism, and'directed Within said cylinders. toward the xignition means. a r

' It is finally an object of this in'yention to construct a device for priming the cylinders of an engine consisting of few parts, and

particularly, so assembled as to facilitate ready attachment and easy removal to or from an automobile orother vehicle or support upon-which the same maybe connected.

The invention in a preferred form) is hereinafter more fully described and defined in the accompanying drawings and specification.

illustrating a modification of the union ele-- ment of Fig. 9. Fig. '12 is a detail section partly inelevation taken on line 12-12 of spectivelyas '2, 3, 4', and 5. A union connecis i cook tion 6, is threaded into each one of said cylinders, and in each case said connection at its 11 per end has threaded therein a pet f. 'A relatively long pressure cylinder 8, is mounted in the dash 9, of the automobile and is supported therein through an aperture therthrough in inclined position by a pair of washers 10 and 11, respectively, the faces of each of which are angled for the purpose, as mentioned, of maintainingthe cylinder 8, in inclined position. At its point of attachment said cylinder 8, is slightly reduced in diameter on its outer periphery in order to project through the apertures in said washers 10 and 11, and afford a shoulder against which said washer 10, may abut to limit the projection ofsaid cylinder 8, therethrough. As shown in Fig.

7, the reduced end of said cylinder 8, is also provided with a longitudinal slot 12, slidably engaged by a pin 13, secured on the washer 11, to prevent rotational movement between the cylinder and the washer, and threads are also provided on the outer reduced end of said cylinder to receive a clamping nut 14, thereon.

' Whenthe device is mounted 'in the dash or other support the washer 10, ispositioned on one side of the dash, and the washer '11,

and is provided with a set screw 17, adapted 1, to engage in an indent 18, in the extremity of said plunger to maintain the finger'grip in the position as shown in Fig. 2, and to release the same into a position as shown in Fig. 7, to permit insertion of the washers 10 and 11, and clamping nut 14, thereover when desired; The outer-surface or periph-' 5 cry of the cylinder 8, beyond that portion extending through the washers and nut already mentioned, is of hexagonal contour, as shown clearly in Figs. 3, 4, and 5, as this enables a purchase to be obtained upon'the cylinder to retain the same from rotation when the clamping nut 14, 1s belng threaded thereon. a

Suitable packing 19, surrounds the plunger, avithin the upper end of the cylin- 4 'der and is retained by apacking gland'20,

threaded. within 'said .cylinder and bearing against the packing. A hollow nut or union 21, is threaded into a suitable aperture in said cylinder 8, and contains a spring pressed ball 22, affording a check valve impelled downwardly by a: spring 23, the upper" end of which seats against a ball 24,

which is free to move upwardly and loosely through the aperture in'said cylinder.

As clearly obvious,'the purpose of the ball 24-, is'merely to aiford seating means for; the

spring 23, whereby the ball closure 22, may

be normally impelled into a position to. close communication through the passage in said union element 21. In order to release the ball 24, whereby pressure within the'in'take fuel supply line 25, may raise the elements contained in said union 21, to permit a flow of fuel therepast, said plunger 16, on its under sideis provided with a relatively long recess 26, so that as thec'urv d shoulder 27, at one end' thereof, passes over the ball 24, as the plunger is drawn outwardly, the ball -24, will spring upwardly into contact with the recessed portion of the plunger, thus releasing the pressure on said spring 23, and

permitting the pressure in' the gasolene line .to the carbureter toprevent a reverse flow through said pipe 25. For the purpose of limiting the amplitude of movement of said plunger 16, a stop 28, is threaded 'into the under sideof said cylinder andfprojects into the recessed portion 26, of the-plunger, and is adapted to contact the shoulder, 29, at the end of said recessed portion 26, to limit the outward adjustment of said plunger. As

shown, said stop element 28, is threaded into the cylinder, thus permitting the same to be.

removed therefrom when it is desired to withdraw the plunger entirely from the'device for any purpose whatsoever. Threaded into said cylinder 8,"on the upper side thereof, is a plurality of. union connections corre- .sponding in number to the number of cylinders on the motor, and denoted respectively by the reference characters 2*, 3 4 and '5,

and are connected by suitable pipes 2", 3", 4", and 5*, to unions 30, one eachthreaded into the union 'elements 6, heretofore mentioned, which are, in turn, secured in the respective cylinders 2, 3, '4, andfif Com tained within each vof said' union elements 2 3, 4, 5, and 30, are spring pressedball or check valves 31, and 30?, respectively, which prevent a reverse flow into the cylinder 8, from any of the respective pipes connected to said' elements. A peripheral t res?? groove 32, "is provided inisaid plunger element l6, and-affords communication for a fiow'of fluid from the recessed portion-26, to a recessed or flattened portion 33, on the upper surface of said plunger element. v Likewise 1t is to be noted that .the end of the plungdr element 16, beyond the shoulder 2.9,

plunger is moved Within the cylinder.

heretofore mentioned, is reduced-in. else- 'eter, in order topermit an easy flow of fluid side or '"the plunger. element, is of a length.

less than thedistance between the apertures thelupper side ofthe cylinder 8, {into which said union elementsare threaded, so

as to at no time permit communication be tween adjacent passages through said ref cessed po'rtion33, of the plunger. A recess 33*, is formed within the cylinder 8, adjacent to and communicating with the outlet to the union connection 2., in order .to pre-fl vent the occurrence of excessive pressure which would otherwise be the result within the cylinder to prevent movement of the v back into its extreme. outer position prior to plunger, when the plunger has been drawn an initial forward movement. This is due to the fact that the recess 33, is withdrawn past the outlet 2, and inasmuch as the cylinder 8, is filled with liquid which is pracr tically incompressible, the initial movement of the plunger would be resisted due to the incompressibility of the fluid. Such a condition, however, isohviated by the provision of the recess 33*, which effects communication between the recess 33, ofthe plunger and the outlet 2, whenthe plunger is'withdrawn into its extreme outer position.

The relatively large union elements 6,

which are threaded into the heads of the motor cylinders. are each provided with passages 34.0Jnd 35, respectively, the passage 34. affording communication between the cylinder and the pet cock '7, and the passage 35, adapted to receive the fluid from one of the aforementioned pipes through theunion 430,130. spray the same into the cylinder, and ';accordingly the lower. end of said passage I "35, is narrowed to-insure the introduction of the fuel into the cylinder in a sprayed condition. In the modification illustrated" in Fig. 11, a laterally directed passage 36, com

municates with th e-passage 35, whereby the fuel may be sprayed laterally in'the cylinder and preferably toward the spark plug or other ignition means, and, of course, a'suitable mark or 1nd1cat1on may he LHOVlClQlOll the upper visible portion of the-elements to; designate the position of saidlaterallydi" rect'ed passage 36, within the cylinder.

The operation isas follows: The. device,

as shown in the position -illustrated in Fig.- 2, is closed, and no flow of fluid takes olace lamaware that var ous details of con- 130 ily be overcome.

thrnethrough. However, when itis desired 3 to prime the cylinders of. the motor, the plunger 16,--i actuated back and forth whereupon the following sequeneof operations take place with each completefimove ment thereof. As the shoulden-2'T onthe plunger passes overzthe ball 24, the same is released, thereh y 'releasing jithe tau closure 22, and permitting the fuelx fromthe inlet supply line 25, to flow "upwardly and into. qthe plunger cylinder '8, and, of course, with the plunger fully. retracted. a considerable quantity of r'uelmay be .;contained therein. .When "the plunger is thrust inwardly into. the cylinder 8, thecontained fluid is, of, course, placed under a condition of pressure, owing to said valve 22, connected to the inlet, being closed, and consequently a flow from the cylinder 6,. can only take place through one of the union valve elements 2, 3, 4 or 5*, depending, of co-urse,"with which valve thereof, the flattened; or recessed portion 33, of the plunger element is .in register. I 4 It-is obvious that as the plunger is moved from its retracted position inwardly within the cylinder that the recessed portion '33, will successively communicate with the passagesleading to each of the aforesaid union 'valvefelements, thus'forcing a certain quantity of .i'uel to the corresponding cylinders of the engine to which said elements are -'connected, and, of course, to only one cylinder at atime. By repeating the opera- .tion of moving the plunger in and out in its:

containing cylinder any desired amount of fuel may be pumped to'the engine cylinders,

and any back pressure due to, compression Hi one or more of the cylinders, may readlnasmuch as 1t .1s desirable to force fuel to only onev cylinder at a time and this' operation onlyv taking place. when therecessed portion'33, of the plunger element is in register with one of the pas 11o sages for certain of said union valve elements, said plunger element must act at all other times to maintain said passages closed.

For thispurpose a spring pressed ball 37,

is provided contained within a hollow threaded plug member 38, which is threaded into the lower side of the cylinder 8, in a position such that the 11211137, may bear up-a wardly against the recessed portion 36, o:E

' the plunger, and thus force the plunger into close contact with the passages in the upper side of the ntlmder to maintain the same closed. v 1 Theplung'er may be withdrawn into retracted position desired and left thus for operation 1? an emergency, the relation be tween the ressure cylinder and the motor cylinder ofcourse being the same when the plunger is In retracted 'positlon'as Whenm normal position.

,struction may be varied through a wide range Without-departing from'the principles of'this invention; I' therefore do not pur: pose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

'1.
